The results for the refractive indices dispersion, optical activity, electro- and piezooptic effects, thermal expansion and the ultrasonic wave velocities for LiKB4O7 crystals are presented. A structural phase transition is revealed at the temperature T=223K.

Keywords: KLiB4O7 crystals, refractive index, electrooptic and piezooptic effects, thermal expansion, ultrasonic wave velocities.
